First thing how big is your  Database ?
HOw much down time you can afford ?
Most easy effecient way,  
                          Create new Oracle 9i home and Database with the 
tablespaces as 
                                     your current 8i database. 
                           Full Export from 8i and  Full importl into  9i. 
Followin g document can help you.

DB_BLOCK_SIZE is 8K, can not reduce that.
do u have simple steps for upgrade manually.
like setting oracle_home to 9i and run upgradeXXX.sql

First. Lets  look at the explanation to ORA-000064 error  dose it make sense.  
  ORA-00064: object is too large to allocate on this O/S num, numCause: The 
initialization parameter DB_BLOCK_SIZE is set to a value that calls for more 
contiguous space than can be allocated on the operating system being used. 
Action: Reduce the value of DB_BLOCK_SIZE so that the requested contiguous 
space is within the capacity of the operating system.
Secondly.  Check the alert log and it will help you in understanding the 
sequence of events as they occured and  after the error what happen did the 
database shutdown or crashed  etc. 
Fix the DB_BLOCK_SIZE and d o the investigation of the cause of error and 
restart the process. 
Finally.  I hope you have a good backup  cold and export of your 8.1.7  
database, before you had started your upgrade project.  If not still not lost 
much take backup FIRST. 
Good Luck.
